Abstract

L'invention concerne un dispositif d'alimentation en matériau en feuille qui permet une réduction de la consommation d'énergie, présente une durabilité améliorée et transporte un matériau en feuille avec une précision élevée. Ce dispositif d'alimentation en matériau en feuille 101, qui transporte un matériau en feuille serré par un premier rouleau 103 et un second rouleau 104, est équipé d'un mécanisme de libération 112 pour libérer le matériau en feuille serré, le mécanisme de libération 112 ayant une came excentrique 201, un palier de came excentrique 202 disposé le long d'une surface latérale de la came excentrique 201, un guide 203 agencé de façon à pouvoir entrer en contact avec le palier de came excentrique 202, et un bloc 204 agencé de façon à pouvoir entrer en contact avec le guide 203 et relié à un élément de support de rouleau supérieur 110. Le mécanisme de libération 112 amène la came excentrique 201 à tourner et déplace le guide 203 dans une direction horizontale par rapport au bloc 204 au moyen du palier de came excentrique 202, amenant ainsi l'élément de support de rouleau supérieur 110 relié au bloc 204 à se déplacer dans le sens vertical.
